 should definitely check out and use if it suits your needs.  This crate has the
 following differences with hlua:
 
-    * Handles to Lua values use the Lua registry, not the stack
-    * Handles to Lua values are all internally mutable
-    * Handles to Lua values use non-mutable borrows the main Lua object, so
-      there can be multiple handles or long lived handles

 The key difference here is that rlua handles rust-side references to Lua values
 in a fundamentally different way than hlua, more similar to other lua bindings

 become feature complete with that API over time.  Some capabilities that API has
 that are on the roadmap:
 
-    * Proper coroutine support
-    * Lua profiling support
-    * Execution limits like total instruction limits or lua <-> rust recursion
-      limits
-    * Security limits on the lua stdlib, and general control over the loaded

-    * "Context" or "Sandboxing" support, this was probably a bit too heavyweight
-      in Starbound's API, but there will be the ability to set the _ENV upvalue
-      of a loaded chunk to a table other than _G, so that you can have different

 There are also some more general things that need to be done:
 
-    * More fleshed out Lua API, things like custom metatables and exposing the

-    * MUCH better API documentation, the current API documentation is almost
-      non-existent.
-    * Performance testing.

 Additionally, there are ways I would like to change this API, once support lands
 in rustc.  For example:
 
-    * Once ATCs land, there should be a way to wrap callbacks based on argument
-      and return signature, rather than calling lua.pack / lua.unpack inside the
-      callback.  Until then, it is impossible to name the type of the function
-      that would do the wrapping.
-    * Once tuple based variadic generics land, the plan is to completely
-      eliminate the lua multi macros in favor of simple tuples.

 of the crate "Work In Progress".  The GOAL is for the crate to handle tricky
 situations such as:

-    * Lua stack size checking, and correctly handling lua being out of stack
-      space
-    * Leaving the correct elements on the lua stack and in the correct order,

 The library currently attempts to handle each of these situations, but there
 are so many ways to cause unsafety with Lua that it just needs more testing.
